> I also took inspiration from ChromeOS's replacement of Caps with Search 

Hah, I do the exact same thing for the exact same reason on every new Mac/Win/Linux machine for almost a decade now. Karabiner on MacOS and PowerToys for Windows.

It’s always nice when it’s supported directly in Linux distros but sometimes have to remap it with config files or a helper tool.

On my MacBook I use Alfred now for search and Win11Debloat for Windows which ensures apps load near instantly when typing.
